Enable bbr on Ubuntu 16.04

Make sure kernel version is 4.9 or newer:
```
uname -r
```
Install Hardware Enablement Stack (HWE) to update kernel automaticly:
```
apt install --install-recommends linux-generic-hwe-16.04
```

Enable bbr:

modprobe tcp_bbr
echo "tcp_bbr" >> /etc/modules-load.d/modules.conf
echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf
echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf
sysctl -p

Check if bbr is enabled:

sysctl net.ipv4.tcp_available_congestion_control
sysctl net.ipv4.tcp_congestion_control
lsmod | grep bbr

Need reboot after Step 1: reboot or sudo reboot

I don't think that's needed after sysctl -p

How can I enable other variants of BBR like Tsunami or BBR+ ?
